  • Help - trying to rewire welder for 208v instead of 240v
    At my house I have 240v service, but since my shop has 3 phase the nominal voltage is 208 . There are no schematics inside the welder anywhere, and the lower amp transformer that has all the …

  • Self Help Forums - Some electrical questions
    Similarly 220V/230V/ 240V are spoken interchangably. As mentioned above, the 208 V is a voltage available on a 208V/120V 3 - phase WYE system. In terms of all current returning to the transformer via the neutral, this is NOT true.
